IMPROVEMENT IN WINDOW-SCREENS.

Specification forming part of Letters Patent No. 211,962, dated February4, 1879; application filed January 4, 1879.

To all whom it may concern:

Be it known that I, GHAUNOEY B. Bosr- WIGK, of Pittsburg, in the countyof Allegheny and State of Pennsylvania, have invented certain new anduseful Improvements in Window-Screens; and I do hereby declare that thefollowing is a full, clear, and exact description of theinvention, whichwill enable others skilled in the art to which it appertains to make anduse the same, reference being had to the accompanying drawings, and toletters of reference marked thereon, which form a part of thisspecification.

The nature of my invention consists in the construction of an adjustablefolding windowscreen, to be constructed of two or more parts, andconnected bymeans of canvas or any other suitable material.

Figure 1 represents an elevation of my improved screen. Fig. 2 is ahorizontal section on line A B, Fig. 1. Fig. 3 is a perspective view ofmy improved window-screen folded.

To enable others skilled in the art to make and use my invention, I willproceed to describe more fully its construction and operation.

a to represent the frames and screens, and B the canvas by which theyare connected together.

In the construction of the screen a a Itake a piece of wire screen ofthe size required. I

incase it in frames either by a groove or by rabbeting, so as to make itperfectly secure.

The screen is made adj ustable to any sized window by connecting two ormore parts by means of canvas, B, fitted into the frame-work a. a of thescreen by a grooved or rabbeted piece. When thus connected together thestrip of canvas B which connects the screens a a is of such a width aswill allow of the screens a a. to be drawn apart, so as to fit thewindow. I prefer to make the strip twoinches in width.

The strip of canvas B is of the same length as the frame of the screen aa, so that when the window is raised the screen placed in the windowfits into the recesses in the side of the window-frame. The sash is thenlowered onto it, holding it securely in its place.

Having thus described my invention, 1 claim- The adjustable foldinginsect-screen for windows in two or more parts, a a, connected by meansof canvas B, as described, for the purpose specified.

In testimony that I claim the foregoing as my own I affix my signaturein presence of two witnesses.
